Display Port --> HDMI - no sound

I have connected my t410 to my HD TV using a DP->HDMI adapter, but the TV has no sound. do you think this is a problem with my computer, which when connected says that HDMI sound is on and all the way up, my DP connection, the adapter i am using, or my TV?

Re: Display Port --> HDMI - no sound

thats a really old thread though.... i'm pretty sure that the DP on my t410, which is about 2 mo old, has sound-- it has a level/mute for HDMI when the DP is connected to the HDMI adapter-TV

Hello panerjeffrey,

 

please read the mentioned post carefully.

 

Then you´ll ackknowledge, the DP has sound, but you´ll need a connector cable of good quality.

Re: Display Port --> HDMI - no sound

First go to your audio settings by going FN + F6, choose "Audio Defaults + Settings". Then choose your TV as the default audio.

 

Now the sneaky part. Push FN + F7 and choose "Projector Only", then sound will come out of the TV. Took me forever to figure out.

Well..  I bought a cheap DP to HDMI connector on ebay for $8.95 including free shipping.  It works flawlessly on my T510 with sound on my LCD TV.

Re: Display Port --> HDMI - no sound

I have the same issue and i followed your instruction. However, Once i went to "Audio Defaults + Settings", I saw only speaker as an option. There is no TV there. Could you pls advice?

 

Thank you

I'm running a W510 and I went to Control Panel > Sounds and Audio Devices > Audio Tab > Sound Playback and selected "NVIDIA High Definition Audio" for the default device and the audio now comes out of the speakers on my Panasonic TV.

Re: Display Port --> HDMI - no sound SOLVED

I have a Thinkpad W520 and I bought a displayport to HDMI dongle and was able to get video but no audio on my TV. I went to control panel and it did not see any hdmi sound device installed. This same displayport to HDMI dongle when used on my friend's Dell Laptop (which also has a dsiplayport and no HDMI out) provides both video and audio on his TV.

 

I recently bought the Lenovo recommended SIIG displayport to HDMI dongle and I now get both video and audio to my TV. It fact it even defaulted to the HDMI sound so I didn't need to go to control panel > sound to manually set it up

 

So there are dongles and other dongles and they aren't all compatible witht the lenovo laptops. below are the lnks for the SIIG dongles $30  that seem to work

 or from lenovo
